Suicide Survival is a modification of Half-Life 2 Deathmatch. There are two teams. You either play as an overweight WW2 pilot in the survivor team or as a suicider disguised as a pot plant in the suicider team. The goal for the survivors is to stay alive and to spot the suiciders. They have a couple of throw-able copies of the book: “Gardening for Beginners – by Barbara Bush” as a self-defense weapon. The goal for suiciders is to sneak up close enough to the survivors in order to blow themselves up. Because each map is full of shrubberies its very hard to spot a real suicidal pot plant among the many fake ones. If a shrubbery isn’t moving, you can’t tell if he is being controlled by another player or not. Currently the game doesn’t have any other goal then being simple team deathmatch. However it still is a lot of fun and you should definitely try it out with a few friends.

Since the update to the new Steam version players who want to host a Suicide Survival server with the "Team Fortress 2 Dedicated Server" tool are greeted with the following error message: SetupArrayProps_R: array prop '(null)' is at index zero.

The reason for this is that the engine build used by the Orange Box DSes on Steam (one for TF2 and each of the Steamworks mods) differs from the one that Suicide Survival was built with (the 2007 SDK code). However there is a solution:

This is a step-by-step guide on how to host your own dedicated server. PS: this will probably also work for other mods with the same problem.

STEP ONE

Download the HLDS Update Tool, which installs a standalone dedicated server. This doesn't require Steam to be running, but also doesn't read data that Steam has downloaded -- meaning that it requires a separate install of the game your are running from, including all textures and sounds. If you don't have 2.5GB free space on your hard drive you're out of luck.

Once downloaded run the hlsdupdatetool.exe and choose a install directory on your hard drive.

STEP TWO

Getting the necessary files to run the server:

Open a command prompt.

Go to Start, Run and type "cmd" (minus quotes) and press enter.

Change to the directory where the HLDS Update Tool is installed.
If you're unfamiliar with the commands here is exactly what you'll have to type:
> cd c:\
> cd (the install directory usually its HLServer so type: cd hlserver)
